Abstract (en)
[origin: EP2903227A1] The present invention relates to a method for operating a base station (11) in a wireless radio network (10). The base station (11) comprises a plurality of antennas (12) for transmitting radio frequency signals between the base station (11) and a user equipment (UE1, UE2, UE3). According to the method, a transmission slot (47) is provided for receiving at each antenna (12) of a subset of the plurality of antennas (12) a training signal sent from the user equipment (UE1, UE2, UE3). For each antenna (12) a corresponding configuration parameter is determined based on the training signal received at the corresponding antenna (12) and payload information blocks (36,37) to be transmitted between the base station (11) and the user equipment (UE1, UE2, UE3) are transmitted using the determined configuration parameters for the antennas (12). A deterioration parameter indicating a deterioration of a transmission between the base station (11) and the user equipment (UE1, UE2, UE3) due to a change in the transmission requiring adaption of the configuration parameters is determined. Based on the deterioration parameter, a timing parameter is determined for controlling when a further transmission slot (47) is to be provided for receiving at each antenna (12) a next training signal sent form the user equipment (UE1, UE2, UE3).
